About FPSTest.org
FPSTest.org is a browser-based platform that helps you measure, understand, and troubleshoot display performance. Whether you're checking FPS (Frames Per Second), testing your monitor's refresh rate, finding dead pixels, or trying to recover a stuck pixel, our tools give you quick results without installing software.
Our goal is simple: make display testing easy for everyone.
Many people notice choppy gameplay, blurry motion, or unusual screen behavior but aren't sure what's causing it. The problem could be low frame rates, an incorrect refresh rate, a stuck pixel, or another display issue. We built FPSTest.org to help you identify those problems with simple tests that run directly in your browser.
What We Do
FPSTest.org provides a growing collection of display diagnostic tools designed for gamers, creators, students, and everyday computer users. Each tool focuses on a specific part of screen performance and explains the results in plain English.
Our platform currently includes:
- FPS Test – Measure your browser's delivered frame rate and compare it with your selected refresh rate.
- Refresh Rate Test – Check your display's measured Hz, frame interval, and timing stability.
- Dead Pixel Test – Find dead, stuck, and bright pixels using full-screen color patterns.
- Dead Pixel Fixer – Try browser-based color cycling that may help recover a stuck pixel.
Instead of showing only numbers, our tools explain what those measurements mean and what you should do next.
How Our Tools Work
Our tools use modern browser technologies to measure frame timing, refresh cycles, and display behavior in real time. They run locally in your browser, so you don't need to download software or create an account.
Depending on the tool, you may see measurements such as:
- Delivered FPS
- Refresh Rate (Hz)
- Frame Interval (milliseconds)
- Timing Variance
- 1% Low FPS
- Stutters
- Skipped Frames
- Pixel Coordinates
These measurements help you understand whether your display is performing as expected instead of relying only on the monitor's advertised specifications.
Why Display Testing Matters
A smooth display experience depends on more than a high refresh rate. Factors like frame pacing, signal bandwidth, VSync, display settings, HDMI, and DisplayPort can all affect what you actually see on screen.
For example:
- A 120 Hz monitor may perform differently if the wrong cable is connected.
- A 144 Hz display may fall back to 60 Hz because of operating system settings.
- A bright spot on your screen may be a stuck pixel rather than a permanently dead one.
Understanding these differences helps you make better decisions before changing hardware or filing a warranty claim.
Built for Real Users
We designed FPSTest.org for people who want quick answers, not complicated technical manuals.
Our tools are useful for:
- PC gamers checking smoother gameplay
- Competitive players testing high-refresh monitors
- Laptop users verifying display settings
- Content creators checking motion clarity
- Anyone inspecting a new monitor for pixel defects
Every tool follows a simple workflow so you can start testing within seconds.
Our Approach
We focus on three principles when building every tool.
Accuracy
We measure real browser behavior instead of displaying generic estimates. Whenever possible, we compare your results with common display standards such as 60 Hz, 120 Hz, 144 Hz, 165 Hz, and 240 Hz.
Simplicity
Technical terms like frame interval, timing variance, and RGB subpixels can be confusing. We explain these concepts in plain language so the results are useful even if you're not a display expert.
Transparency
We avoid making unrealistic promises. For example, a stuck pixel may respond to color cycling, but a permanently dead pixel usually cannot be repaired. Our tools explain these limitations clearly.
Privacy
Your testing sessions stay on your device. Our browser-based tools perform measurements locally and do not require you to upload your screen or install additional software to run the tests.
Looking Ahead
Display technology continues to evolve with higher refresh rates, faster panels, OLED screens, and new connection standards. We plan to keep expanding FPSTest.org with more tools, better diagnostics, and clearer explanations that help you understand how your display performs in everyday use.
Whether you're checking FPS before a gaming session, confirming your monitor's refresh rate, or inspecting a new screen for pixel defects, FPSTest.org gives you practical testing tools that are fast, simple, and built for real-world display troubleshooting.
